[apologies for duplicates] Hello, At the recent RIPE Meeting in Prague, Marco Hogewoning presented the IPv6 CPE survey he conducted among various vendors. The results are now published on RIPE Labs. You can find it on the home page http://labs.ripe.net or you can go directly to: http://labs.ripe.net/content/ipv6-cpe-survey In order to keep this survey up to date, we are looking for feedback: If you have access to a testbed, are already running tests of your own or if you spot an error, please leave a comment in the IPv6 CPE Survey forum: http://labs.ripe.net/content/ipv6-cpe-survey-0 or contact us at labs at ripe dot net Kind Regards, Mirjam Kühne RIPE NCC

Upstream BGP community support
by Andy B. 04 Jun '10

04 Jun '10

Hi, Quick question: Would you buy transit from someone who does not support BGP communities? Here is the story: My company is pushing several GBit/s through various upstream providers. We have reached the point where we rely on BGP communitiy support, especially communities that can be sent to the upstream to change the way he announces our prefixes to his peers/transits. While most decent upstream providers support this kind of traffic engineering, one of them refuses to send and accept BGP communities. I tried to contact my upstream several times through different channels to get some background as to why they would not be able to provide us this service, but all we get is tickets that get closed without an answer. Management itself does not seem to bother either. Is this normal or is it too much to ask for BGP communities from an upstream who has points of presence in the US, Europe and Asia? Andy

AS 7575 announcing 2400::/12
by Geoff Huston 03 Jun '10

03 Jun '10

Hi, As part of some ongoing collaborative research work in looking at the "dark" traffic in IPv6, APNIC has requested AARNet to originate a supernet advertisement of the IPv6 prefix 2400::/12 for the next two weeks. The originating AS is AS7575. We would appreciate it if you could adjust your routing filters to permit this advertisement if you are actively filtering IPv6 routing advertisements. Reports from previous work in the IPv4 space can be found at http://www.potaroo.net/studies/ - we hope to add to this with a report describing data collected about the level (and type) of background traffic seen in this part of IPv6. We would also be grateful if other operational lists received this notification - so please forward this as appropriate (but preferably only once!) Many thanks, Geoff Huston, George Michaelson APNIC
